Re: comedi and redhat 9.0? (HOW TO DO IT)

OK I just found another patch you need to apply to the code for RedHat 9

You need to change the call to "pte_offset" in drivers.c to be 
"pte_offset_kernel"

SO in summary...
   1) Run 'make mrproper' before you do 'make oldconfig' for kernel
   2) Patch comedi_fops.c and add "vma" as a new first argument to the 
remap_page_range() call.  It
       changes from...
           if(remap_page_range(start, __pa(async->buf_page_list[i]),
        to look like...
           if(remap_page_range(vma, start, __pa(async->buf_page_list[i]),
   3) Patch drivers.c and change "pte_offset" to "pte_offset_kernel"
